Product FAQs
8 answersWhat type of terminations does the JGP36250 include?
The P in the JGP36250 catalog number indicates it is equipped with line-side terminal nuts and load-side lugs. The load lugs accept 3/0 AWG to 350 kcmil aluminum or copper wire.
Which Square D panelboards accept the JGP36250 breaker?
This unit-mount PowerPacT J-Frame breaker is designed for installation in Square D NF panelboards, NQ panelboards, QED switchboards, and industrial control panels. It is a bolt-on breaker and will not fit I-Line panelboards.
What does the G in the JGP36250 catalog number represent?
The G indicates the interrupting rating of the breaker. For this PowerPacT J-Frame model, the G rating provides a 65kA capacity at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Are the trip settings on the JGP36250 adjustable?
Yes, this breaker features a thermal-magnetic trip unit with fixed thermal protection and an adjustable magnetic trip setting for short-circuit protection.
Can the JGP36250 be used in DC electrical systems?
Yes, it is rated for use in DC applications up to 500VDC. It provides a 20kA interrupting capacity at both 250VDC and 500VDC.
What is the difference between the JGP36250 and JGL36250 circuit breakers?
Both are 250A, 3-pole PowerPacT J-Frame breakers with a G interrupting rating. The difference is the termination style. The JGP36250 has line-side terminal nuts and load-side lugs, while the JGL36250 is equipped with lugs on both the line and load sides.
Is the JGP36250 considered a current-limiting circuit breaker?
Yes, PowerPacT J-Frame breakers utilize dual-break rotating contacts that reduce the amount of peak current during a short-circuit fault, providing current-limiting protection.
Does the JGP36250 have a manual trip feature for testing?
Yes, PowerPacT circuit breakers include an integral push-to-trip button on the cover, allowing you to manually trip the breaker to verify the operating mechanism is functioning correctly.
